Cupping is one of the most common treatments. How long can you take a bath after cupping is mainly related to the patient’s reaction after cupping. Cupping will cause the pores of the skin to open, so bathing at this time will cause the cold to invade the body and cause diarrhea due to the coldness of the spleen and stomach. After cupping, the pores of the skin gradually close and the patient can take a bath after 3-6 hours. If the skin is blistered or if the cupping marks are deep and blackish-purple, it is recommended to take a bath the next day, and the water temperature needs to be adjusted upwards. In addition, after cupping treatment, patients should avoid staying in air-conditioned rooms for too long, wear soft textured clothes to reduce friction on the skin and keep the local skin clean. Avoid stimulating and spicy foods, eat more vegetables and fruits, and replenish their vitamins and calcium, etc.
